Picture a man who has done everything right. Years ago he sat down with an attorney and signed a will leaving everything to his two children, equally. He never remarried after his divorce, and he never thought about the 401(k) he opened at his first job. When he passes away, his children discover that the retirement account lists his ex-wife as the beneficiary. The will does not matter. The account goes to her.
This surprises almost every family that experiences it, and it happens more often than people think. A will is one of the most important documents you can sign, but it does not control everything you own. Some of your largest assets may pass by a different set of rules entirely, and the paperwork you filled out years ago, sometimes in a few minutes, can decide where they go.
Two Ways Property Passes at Death
When someone passes away, their property generally moves in one of two ways.
Probate assets pass under the will, or under New Mexico's default rules if there is no will. These are assets in the person's name alone, with no beneficiary named and no co-owner who automatically takes over. A personal representative (executor) handles them, usually with court involvement.
Nonprobate assets pass outside the will, by contract or by how the property is titled. They go straight to the person named on a form or to a surviving co-owner, without going through the will at all. Common examples are retirement accounts, life insurance, annuities, and bank or investment accounts set up to pay a named person at death.
The key point is this: your will only controls the first group. If most of what you own is in the second group, your will may govern very little. A carefully written will cannot redirect an asset that already has a different instruction attached to it.
Why the Designation Wins
It helps to understand what a beneficiary designation actually is. When you open a retirement account or buy a life insurance policy, you sign an agreement with the company that holds the money. Part of that agreement says who receives the funds when you pass away. The company is required to follow the agreement. It does not read your will, and it does not care what your family expected.
New Mexico law supports this. Instructions of this kind, in insurance policies, retirement plans, bank accounts, and similar agreements, are treated as taking effect outside the will. They are a separate way to leave property, not a gift made in a will.
For many employer retirement plans, federal law adds another layer. In those cases, the plan generally pays whoever is named in the plan's own records. Courts have enforced that rule even when a divorce decree or other document said something different. The practical lesson is the same: the name on the form is the name that counts.
Which Accounts Work This Way
Look for beneficiary designations, or something like them, on:
- Retirement accounts: 401(k), 403(b), IRA, pension, and similar accounts
- Life insurance: both individual and employer-provided policies
- Annuities
- Payable-on-death (POD) accounts: bank accounts that pay a named person at death
- Transfer-on-death (TOD) accounts: brokerage and investment accounts with a named beneficiary
- Joint accounts with survivorship: when one owner passes away, the other owner takes the account
- Transfer on death deeds: a recorded deed that passes real estate to a named person at death. We explain these in our FAQ on transfer on death deeds in New Mexico.
If you are not sure which of your accounts have beneficiaries, a good starting point is to make a list of every account, then call or log in to each one and look.
Joint Accounts Can Surprise Families Too
Beneficiary forms are not the only way an asset can skip your will. A joint account with survivorship usually passes to the surviving owner, no matter what the will says. That is often the goal for spouses. It can cause problems when a parent adds one child to an account "for convenience," so that child can pay bills. Without a clear understanding, that child may end up with the entire account at the parent's death, and the other children may feel left out. If you have added someone to an account, ask yourself whether you meant for them to have it, or only to help manage it.
Your Will Still Matters
None of this means a will is unimportant. It governs everything that is in your name alone with no beneficiary, it is where you name guardians for minor children, and it is the safety net for anything you forgot to address. The goal is not to choose between your will and your forms. It is to make sure they work together, so that each one supports the plan you actually have in mind.
Common Mistakes
Most beneficiary problems come from a small group of mistakes.
The ex-spouse is still listed. This is the most common and most painful. New Mexico law says a divorce generally cancels gifts to a former spouse in a will and in certain other documents. But that rule does not always reach every account, and for some employer plans, federal law can override it. Never assume a divorce took care of your forms. Update them.
The beneficiary has already passed away. If the person you named is gone and you never named a backup, the account may pass under the plan's default rules, which can send it to your estate. That can mean probate, delays, and in some cases less favorable tax treatment.
No one is named. Many people skip the form, or never see it. When no beneficiary is named, the account usually follows the company's default order or becomes part of your estate. Either way, the result may not match what you would have chosen.
A minor child is named directly. Children cannot manage large sums of money, and a financial company will not simply hand it over. Naming a child directly may require a court-supervised arrangement to hold the money until the child is an adult, and then the child may receive it all at once. Many families prefer to name a trust, or to speak with an attorney about options.
A beneficiary has a disability or receives public benefits. An inheritance paid directly to someone who receives means-tested benefits can affect their eligibility. A properly drafted trust can protect both the inheritance and the benefits.
The result does not match the plan. A father names his oldest daughter on the life insurance because she handled his care, and the will splits everything equally. The family sees an unfair outcome, but nothing is "wrong." The forms say what they say. If you want an unequal result, make sure it is intentional, and explain it to your family.
The forms were never updated. Marriages, divorces, births, deaths, and falling-outs all change who should be on the form. Most people only update a form when something forces them to.
Taxes and Retirement Accounts
Beneficiary choices matter for taxes, too, especially with retirement accounts. Under the IRS rules, a surviving spouse who is the sole beneficiary generally has the most flexibility, including the option to treat the account as their own. Most other individual beneficiaries who inherit a retirement account from someone who passed away in 2020 or later must withdraw the full balance by the end of the tenth year after death. Certain beneficiaries, such as minor children, people with disabilities or chronic illness, and people close in age to the original owner, may have more options.
Who you name affects how quickly taxes come due, and how much flexibility your family has. Naming your estate as the beneficiary of a retirement account, or leaving it blank, can limit those options. The tax rules are detailed and change from time to time, so talk with an attorney and a tax professional before you make large changes.
Community Property and Your Spouse
New Mexico is a community property state, which means that property earned during a marriage is generally treated as belonging to both spouses. That affects how retirement accounts and life insurance may be treated when a married person names someone other than their spouse. Many employer plans also have special rules, and may require a spouse's written consent before a participant names anyone else.
If you are married and thinking of naming someone other than your spouse, or if you were married when you opened the account, talk with an attorney first. The rules depend on the type of account and the facts of your situation.
How to Fix It: A Checklist
You can start today. Here is a simple approach:
- List every account. Include retirement accounts, life insurance, annuities, bank and brokerage accounts, and any property with a TOD deed.
- Find the current form. Call the company or log in. Ask who is listed as the primary and contingent (backup) beneficiary.
- Compare to your plan. Do the names match what you want today? Does the result line up with your will or trust?
- Name a primary and a backup. Use full legal names, and, if you want to split an account, state the percentages clearly.
- Think about minors and special circumstances. If a beneficiary is a child, has a disability, or may not handle money well, ask about a trust.
- Get written confirmation. Keep a copy of the updated form or the confirmation page.
- Tell someone. Make sure a trusted person knows where the records are.
If your documents include a trust, ask an attorney whether the trust itself should be named as a beneficiary of some accounts. It can be a good approach, but it must be done carefully so that it works as intended.
When to Review
Review your beneficiary designations:
- After a marriage, divorce, birth, adoption, or death in the family
- When you open a new account, change jobs, or buy a new policy
- Whenever you update your will or trust
- At least every few years, even if nothing seems to have changed
A short review can prevent the kind of surprise that no family wants to face while they are grieving.
